Will the slower first quarter -- and RIM's maturing products -- help the company's gross margins improve? Or at least stay level?

RIM's gross margins have fallen to around 40% from more than 50% a year ago, as a result of selling new, more sophisticated phones, and increased marketing spend. Gross margin guidance lower than 40% could send investors running away, while an uptick would be good news.

We're also curious what RIM's management has to say about forthcoming BlackBerry devices; competing with Apple's improved iPhone 3.0 software (due out this summer) and the forthcoming Palm Pre; and the new BlackBerry app platform, which launched yesterday.
